Announcing NetBSD 5.1.3

Introduction

The NetBSD Project is pleased to announce that version 5.1.3 of the NetBSD
operating system is now available. NetBSD 5.1.3 is the third
critical/security update of the NetBSD 5.1 release branch. It represents
a selected subset of fixes deemed critical for security or stability
reasons.

Please note that all fixes in critical/security updates (i.e., NetBSD 5.0.2,
5.1.2, etc.) are cumulative, so the latest update contains all such fixes
since the corresponding minor release. These fixes will also appear in
future minor releases (i.e., NetBSD 5.3, etc.), together with other
less-critical fixes and feature enhancements.

Complete source and binaries for NetBSD 5.1.3 are available for download
at many sites around the world. A list of download sites providing FTP, HTTP,
AnonCVS, SUP, and other services may be found at
http://www.NetBSD.org/mirrors/.
We encourage users who wish to install via ISO images to
download via BitTorrent by using the torrent files supplied in
the ISO image area.
A list of hashes for the NetBSD 5.1.3 distribution has been signed with
the well-connected PGP key for the NetBSD Security Officer:

NetBSD is free. All of the code is under non-restrictive licenses,
and may be used without paying royalties to anyone. Free support
services are available via our mailing lists and website. Commercial
support is available from a variety of sources. More information on
NetBSD is available from our website:

File Systems

Miscellaneous

sparc64: Fixed the root cause of the hack "disable optimizations for
uvm_bio.c on 32 bit kernels."

x68k: Fix the clock when timecounter uses "mfp" (the default)

Update IPv6 DNS servers in sysinst.

MAKEDEV: the console major number is not always 0.

Update some TNF ssh keys in /etc/ssh/ssh_known_hosts.

Known Problems

Using block device nodes (e.g., wd0a) directly for I/O may cause
a kernel crash when the file system containing /dev is FFS and is mounted
with -o log. Workaround: use raw disk devices (e.g., rwd0a), or remount
the file system without -o log.

Occasionally, gdb may cause a process that is being debugged
to hang when "single stepped". Workaround: kill and restart the
affected process.

gdb cannot debug running threaded programs correctly. Workaround:
generate a core file from the program using gcore(1) and pass the
core to gdb, instead of debugging the running program.

Acknowledgments

The NetBSD Foundation would like to thank all those who have
contributed code, hardware, documentation, funds, colocation for
our servers, web pages and other documentation, release engineering,
and other resources over the years. More information on the people who
make NetBSD happen is available at:

We would like to especially thank the University of California at
Berkeley and the GNU Project for particularly large subsets of code
that we use. We would also like to thank
the Internet Systems Consortium Inc., and the Network Security Lab at
Columbia University's Computer Science Department
for current colocation services.

About NetBSD

NetBSD is a free, fast, secure, and highly portable Unix-like
Open Source operating system. It is available for a wide range
of platforms, from large-scale servers and powerful desktop
systems to handheld and embedded devices. Its clean design
and advanced features make it excellent for use in both
production and research environments, and the source code is
freely available under a business-friendly license. NetBSD is
developed and supported by a large and vivid international
community. Many applications are readily available through pkgsrc,
the NetBSD Packages Collection.

About the NetBSD Foundation

The NetBSD Foundation was
chartered in 1995, with the task of overseeing core NetBSD project
services, promoting the project within industry and the open
source community, and holding intellectual property rights on much
of the NetBSD code base. Day-to-day operations of the project are
handled by volunteers.

As a non-profit organization with no commercial backing, The NetBSD
Foundation depends on donations from its users, and we would like to ask
you to consider making a donation
to the NetBSD Foundation in support of continuing production of our
fine operating system. Your generous donation would be particularly
welcome assistance with ongoing upgrades and maintenance, as well as
with operating expenses for The NetBSD Foundation.

Donations can be done via PayPal to <paypal@NetBSD.org> and
are fully tax-deductible in the US. If you would prefer not to use PayPal,
or would like to make other arrangements, please contact
<finance-exec@NetBSD.org>.
